The XML report generated by coverage==3.7.1 shows that classes with no lines (typically __init__.py files) have a line-rate=0 when it should be line-rate=1.

#!xml

<?xml version="1.0" ?>
<!DOCTYPE coverage
  SYSTEM 'http://cobertura.sourceforge.net/xml/coverage-03.dtd'>
<coverage branch-rate="0" line-rate="1" timestamp="1418882048682" version="3.7.1">

When this file is given to pycobertura, it shows:

Wrong title, I wanted to have the title set as "XML reports line-rate=0 for empty files, should be 1". I created the issue while I was signed out but now I can't edit it anymore.
